magnetospheric truncation radius

(radius at which the disc ram pressure matches the magnetic field pressure)

The magnetospheric truncation radius is the radius of the inner edge of an accretion disk where the ram pressure of the disc matches that of the magnetic field. At that radius, material cannot simply continue inward and moves out of the plane of the disk, i.e., through a third dimension, as it continues toward the host object.
